Busch as Interim Chief Executive Officer of Aditxt, Inc., effective May 31, 2026. Mr. Busch, who has served as Chief Executive Officer of Aditxt's CLIA-certified precision oncology diagnostics subsidiary Ignite Proteomics, LLC ("Ignite") since March 2026, will now lead the full Aditxt enterprise as it executes an accelerated commercialization strategy centered on Ignite's precision oncology diagnostics platform.

About Jeffrey M. Busch

Mr. Busch is the Founder, Chairman, and former Chief Executive Officer of Global Medical REIT, Inc. (NYSE:GMRE), now Chiron Real Estate, Inc. (NYSE:XRN), an NYSE-listed net-lease healthcare real estate investment trust that he founded and built to over $1 billion in enterprise value. Throughout his tenure as CEO, Mr. Busch maintained a consistent and disciplined dividend program, delivering an average annual dividend yield of approximately 8.5% to common shareholders — a track record that reflects both his commitment to capital stewardship and his ability to build institutional-grade infrastructure within a regulated, healthcare-focused business environment.

A graduate of the New York University Stern School of Business with a Bachelor of Science in Business, Mr. Busch also holds a Master of Public Administration specializing in health policy from New York University and a Juris Doctor from Emory University. His academic foundation spans law, business, and health policy — a rare combination that has informed both his regulatory approach and his commercial strategy throughout a career at the intersection of healthcare and capital markets.

Earlier in his career, Mr. Busch served as a congressional aide before being appointed by two United States Presidents to serve in their administrations, including as a United States Delegate to the United Nations in Geneva. Since 2001, he has served as President of the Safe Blood International Foundation, overseeing the establishment of medical facilities in 35 developing nations — programs funded by the CDC, USAID, ExxonMobil, and the Gates Foundation. This global health mission underscores a career defined not only by financial performance, but by a genuine commitment to expanding access to life-saving medical care.

"Aditxt and Ignite sit at one of the most important intersections in modern medicine — precision diagnostics and patient-centered oncology care. With approximately 40% of cancer drugs not working for the patients they are prescribed to, the clinical imperative behind what Ignite does could not be more clear. My focus will be on translating that clinical imperative into a commercially excellent, financially disciplined, and patient-first organization. We have a Medicare-reimbursed platform, growing clinical validation, established research partnerships, and a large and expanding addressable market. The work ahead is to build on that foundation with urgency and accountability — to our patients, to our people, and to our shareholders."

— Jeffrey M. Busch, Interim Chief Executive Officer, Aditxt, Inc.

Strategic Priorities Under New Leadership

Under Mr. Busch's leadership, Aditxt intends to advance the following core strategic priorities:

• Patients First, Always. Every strategic and operational decision will be evaluated against a single standard: "does it serve patients and improve their lives?" This commitment is non-negotiable and will govern the Company's culture, capital allocation, and commercial behavior.
• Revenue-Driven Innovation. Aditxt will pursue clinical innovation and commercial performance with equal discipline — deepening the clinical evidence base that supports Ignite's RPPA platform while simultaneously building the revenue infrastructure necessary to fund continued R&D and sustain the Company's mission long-term.
• Responsibility to All Stakeholders. The Company will operate with full transparency and financial discipline — meeting its obligations to employees, clinical partners, vendors, and shareholders, and building an organization worthy of the trust placed in it by every constituency it serves.
• Capital Market Engagement. Drawing on Mr. Busch's experience building and sustaining an NYSE-listed public company, Aditxt will pursue proactive investor relations, responsible capital stewardship, and strategic partnership development to support the Company's growth trajectory and enhance long-term shareholder value.
